Taiwanese travel payment cards featuring the image of Japanese adult video actress Yui Hatano sold out within four hours of going on sale Tuesday.

EasyCard Corp. began taking orders by phone for the cards at midnight and sold out all 15,000 sets at 4:18 a.m., the company said in a statement.

The company apologized again that the cards — racy but without nudity — had caused so much controversy. It said it would amend internal rules regulating the images printed on cards.
